Question No : 1

A customer wants to enable tamper-proof Snapshot copies on volume LockingVolume, which is hosted on SVM LockingSVM. They have created the Snapshot policy, including the required retention set. However, when they apply the policy to a volume, the Snapshot copies are not locked.
Which command must the customer issue before tamper-proof Snapshot copies can be enabled?

A.volume modify -volume LockingVolume -anti-ransomware-state enable
B.volume modify -volume LockingVolume -snapdir-access false
C.snaplock event-retention apply -vserver LockingSVM
D.snaplock compliance-clock initialize -node *

정답:
Explanation:
To enable tamper-proof (locked) Snapshot copies using SnapLock, the SnapLock Compliance Clock must be initialized on all nodes in the cluster. Without initializing this clock, locked Snapshots cannot be created, even if the policy and retention settings are configured.

Question No : 2

Your IT company is using NetApp FlexClone on a two node AFF cluster with 20TB of data to rapidly provision environments for each developer.
Each environment is replicated to an eight node AFF C-Series cluster at a DR site using SnapMirror. You notice that the environments are consuming significantly more disk space on the destination cluster than on the source cluster.
In this scenario, which action will minimize the disk usage on the destination cluster?

A.Consolidate the SnapMirror destination volumes onto a single aggregate.
B.Distribute the SnapMirror destination volumes evenly across the available aggregates.
C.Enable SnapMirror network compression.
D.Enable Flexclone copies on the DR side.

정답:
Explanation:
FlexClone volumes are space-efficient on the source cluster because they share blocks with the parent. However, SnapMirror transfers them as full physical copies by default unless you re-create them as FlexClone volumes on the DR site.
Enabling FlexClone copies on the destination will preserve their space efficiency and minimize disk usage on the DR cluster.

Question No : 3

Which two of the following need to be enabled to use tamper-proof Snapshot copies? (Choose two.)

A.Compliance Clock
B.three NTP servers
C.SnapRestore license
D.NetApp ONTAP One license

정답:
Explanation:
To use tamper-proof Snapshot copies (e.g., SnapLock-based WORM Snapshots):
● The Compliance Clock must be initialized to enforce retention periods that cannot be bypassed.
● A NetApp ONTAP One license includes the SnapLock feature, which enables tamper-proof snapshot functionality.

Question No : 4

An administrator wants to automatically prevent volumes that are used in a SnapMirror relationship from running out of space.
Which of the following volume snapshot autodelete modify parameters would ensure that this goal can be accomplished?

A.-defer-delete scheduled
B.-commitment disrupt
C.-commitment try
D.-defer-delete user_created

정답:
Explanation:
Setting -commitment try on the volume snapshot autodelete modify command allows ONTAP to automatically delete eligible Snapshot copies when a volume is running low on space, but only if it can do so without violating SnapMirror or retention policies. This ensures volumes in SnapMirror relationships stay healthy and do not run out of space unexpectedly.

Question No : 5

After setting up a new cluster peering relationship between a production site and a new DR site, the customer mentions that the communication for this peer needs to be secured to help deter "man in the middle" attacks.
What can you do on the NetApp end to secure the existing cluster peering?

A.Modify the firewall policy settings on the Intercluster LIFs.
B.Enable aggregate level encryption.
C.Modify the relationship using -encryption-protocol-proposed.
D.Enable IPsec between the sites.

정답:
Explanation:
To secure an existing cluster peering relationship, you can modify it to enable encryption by using the -encryption-protocol-proposed option. This ensures that intercluster SnapMirror traffic is encrypted, helping protect against man-in-the-middle attacks.

Question No : 6

You need to upgrade to NetApp ONTAP 9.12.1 software on your source cluster in a SnapMirror relationship. The source cluster differs from the destination cluster and you want to take advantage of version-flexible SnapMirror replication.
Which option should you choose?

A.SnapMirror automatically converts existing DP-type relationships to XDP-type relationships.
B.Run the command snapmirror resync and set the type to XD
C.Delete the XDP-type relationship and create a new DP-type relationship.
D.Delete the DP-type relationship and create a new XDP-type relationship.

정답:
Explanation:
To take advantage of version-flexible SnapMirror (introduced with XDP-type relationships), you must delete the existing DP-type relationship and create a new one using type XDP. DP-type relationships do not support version flexibility, which allows the source and destination clusters to run different ONTAP versions.

Question No : 7

A customer is running NetApp ONTAP 9.14.1 software and asks you to protect some data in a way that even disk zeroing cannot delete.
Which command enforces the requirement?

A.volume create -snaplock-type compliance
B.volume create -snaplock-type enterprise
C.aggregate create -snaplock-type compliance
D.aggregate create -snaplock-type enterprise

정답:
Explanation:
The SnapLock Compliance mode provides WORM (Write Once, Read Many) protection that is irrevocable, even by administrators, and not removable by disk zeroing or reinitialization. This satisfies stringent regulatory and tamper-proof data protection requirements.

Question No : 8

You have created a SnapMirror relationship from your production volume serving SMB/CIFS data to your DR cluster. After two days of updates, you do not see any of the expected snapshots on the secondary volume.
Why is SnapMirror failing to replicate snapshots?

A.The SnapMirror label is missing from the SnapMirror policy on the secondary volume.
B.SnapMirror is not properly licensed.
C.SVM peering is not properly configured.
D.The SnapMirror label is missing from the snapshot policy on the secondary volume.

정답:
Explanation:
SnapMirror replication is driven by labels that match between the snapshot policy on the source volume and the SnapMirror policy. If the snapshot policy on the source does not include the correct SnapMirror label, SnapMirror will not recognize which snapshots to replicate, resulting in no transfers.

Question No : 9

What are the two modes for Autonomous Ransomware Protection (ARP)? (Choose two.)

A.active
B.listening
C.passive
D.learning

정답:
Explanation:
Autonomous Ransomware Protection (ARP) operates in two modes:
● Learning mode: ARP observes and learns baseline workload behaviors to distinguish between normal and abnormal activity.
● Active mode: ARP actively monitors and can automatically respond to ransomware-like behavior by alerting or taking protective actions.

Question No : 10

An administrator is setting up SnapMirror SVM replication. One of the source data volumes uses cloud tiering with the snapshot-only tiering policy.
Which cloud tiering policy is supported on the destination volume?

A.none
B.auto
C.all
D.snapshot-only

정답:
Explanation:
When using SnapMirror SVM replication, the cloud tiering policy on the destination volume must match the source if tiering is to be preserved. The only supported tiering policy in this context is snapshot-only, which moves cold Snapshot blocks to cloud tier. This ensures compatibility during replication.

Question No : 11

You have a large 2PiB flexgroup that will need to be failed over to a DR site for a weekend due to maintenance work at the original site. To speed up time to return to normal operations the Storage Administrator will use the -quick-resync true option when reversing the SnapMirror relationship.
What needs to be taken into consideration when it comes to using quick resync?

A.All storage efficiencies will be preserved
B.All storage efficiencies are done in line with the SnapMirror
C.All storage efficiencies will be ignored
D.All storage efficiencies will be lost on the source

정답:
Explanation:
When using the -quick-resync true option in SnapMirror, storage efficiencies such as deduplication and compression are not preserved on the original source during resync. This means that efficiencies will be lost on the source volume, and data will be rehydrated to its full form during transfer.

Question No : 12

What is the minimal interface requirement for a SnapMirror relationship between clusters?

A.one data LIF per SVM
B.one cable directly connected to both clusters
C.one intercluster LIF per node
D.one intercluster LIF per SVM

정답:
Explanation:
For a SnapMirror relationship to function properly, each node in a cluster must have at least one intercluster LIF. These LIFs are used exclusively for replication traffic and ensure that all nodes can participate in SnapMirror operations.

Question No : 13

Your customer wants to set up a local retention time of at least four months. They also want to protect a week of retention from being deleted by ransomware or rogue administrators.
Which two settings create the correct Snapshot policy to achieve this? (Choose two.)

A.Enable Autonomous Ransomware Protection (ARP) on the volume.
B.Create a Snapshot policy with the weekly Snapshot copy retention time set to 122 days.
C.Create a Snapshot policy with the maximum daily snapshots set to 122.
D.Set the SnapLock retention period for the daily Snapshot copies to 7 days.

정답:
Explanation:
To meet the requirement of 122 days ≈ 4 months, so setting the weekly Snapshot copy retention to 122 days ensures local backups are retained for that duration.
To protect a week of retention from tampering, apply SnapLock to the daily Snapshot copies with a 7-day retention, which makes them tamper-proof and resistant to deletion by ransomware or rogue administrators.

Question No : 14

An administrator has been tasked to replicate data between two NetApp clusters to ensure that the data is replicated no more than once per hour.
Which NetApp solution meets this requirement?

A.MetroCluster SyncMirror
B.SnapMirror active sync
C.SnapMirror Synchronous
D.SnapMirror Asynchronous

정답:
Explanation:
SnapMirror Asynchronous is designed to replicate data based on a scheduled interval, such as once per hour. It is ideal for disaster recovery scenarios where zero RPO is not required but periodic replication is sufficient.

Question No : 15

A VMware Administrator needs to restore a VM after a recent server patch update has corrupted the VM operating system.
What is the quickest way to restore the VM?

A.From vCenter vSphere client, use SnapCenter Plug-In for VMware vSphere to restore the VM
B.From the SnapCenter Server, use SnapCenter Plug-In for VMware vSphere to restore the VM
C.From ONTAP System Manager, create a FlexClone of a Snapshot before the patch update, andmount to vSphere
D.From ONTAP System Manager, rollback the datastore volume containing multiple VMs to a previousSnapshot

정답:
Explanation:
Creating a FlexClone from a pre-patch Snapshot is the quickest, space-efficient method to restore a single VM without affecting others in the datastore. It enables immediate access to the VM’s previous state without a full restore or rollback of the entire volume.
